SPRING-WHEEL.

Specification of Letters Patent.

Patented May 21, 1912.

, Application filed .Tuly 1, 1910. Serial No. 569,897.

1 following is a specification, reference being had therein to theaccompanyingr drawings.

This invention relates to a cushion tire for vehicle wheels in whichprovision for the desired resiliency is made in such manner as toexclude moisture and dirt from the mechanism.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claim.

In the drawings,rFigure 1 is a view in side elevation of a wheelequipped with a tire embodying features of the invention with portionsof a shield partly broken away; Fig. 2 is a view in section, enlarged,on line -w of Fig. 1; Fig. 3 is a view in section, enlarged on lineg/-fz/ of Fig. 1; and Fig. 4 is a view in detail of a coupling member;Fig. 5 is a perspective View of the tension link, assembled butpartially broken away; and Fig. 6 shows a perspective View of one of themembers thereof.

Referring to the drawings, a rim 1 of metal or like suitable material,with an outer face adapted to retain a cushion tread 2 or the like isconcentrically spaced from the inner ring 3 by a series of radiallydisposed springs 4 in compression between them. Lateral displacement ofthe rim is prevented by an outer rib 5 on the ring which plays betweenthe parallel `faces of a fixed ange 6 and removable flange 7 on theinner periphery of the rim. The flange 7 is preferably provided with afoot collar 8 that fits snugly in the rim, and is secured in place as bybolts or the like. Projections or keepers 9 on the proximate faces ofthe rim and ring, retain the springs, the flange 7. being notched toslip past those on the rim.

Rotation of the rim on the ring is prevented by links. These eachconsist of a pair of flat metal strips bent between their ends intoparallel arms 19, 19 connected by shanks 10, 10 respectively. The stripsCopies of this patent may be obtained for are hooked together, theshanks being narrower than the arms so that the resultant notches in themargins of each strip act as guideways for the other strip. A spring 11is in compression between the Shanks 10, 10', and the ends of the stripsare connected by pivot studs 12 or the like to lugs 13 on the rim andlike projections 14 on the ring. Annular flexible covers 15 of suitablematerial connect the correspondin margins of the ring and rim as a diskshie d. Preferably keeper rings 16 and screws 17 secure the bands to therim, the latter being rabbeted around its edges for receiving the rings.The other edges of the bands are held in tapered grooves in the ring bywedgeshaped rings 18. By this arrangement a resilient tire of simpleconstruction is obtained which is readily applied to any wheel of propersize.

Obviously, changes in details of construction may be made withoutdeparting from the spirit of the invention, and we do not limitourselves to any particular form or arrangement of parts.

What we claim as our invention is:

In a cushion tire, the combination with an outer rim having an internalannular guide flange, an inner ring having an eX- ternal annular rib,means for maintaining said flange and rib in sliding engagement witheach other, and springs interposed between the rim and ring and fornormally centering the same relatively to each other,
